1. Go to https://en.wikipedia.org/wiki/Special:Book?bookcmd=load_collection&colltitle=Book:3.1415 2. Edit the name of some chapter 3. Save collection under the name "Book:3.1415" Expected result: Only the changed chapter should be updated Actual result: https://en.wikipedia.org/w/index.php?diff=592952129 i.e. * The category was removed * The template {{saved book |title=3.1415 |subtitle=The Archimedes constant |cover-image=Squaring the circle.svg |cover-color=#ffffff}} was replaced by an empty template {{saved book |title= |subtitle= |cover-image= |cover-color=}}
